Add Room error

[mr physics]

I've managed to install and get it running (added periods, school
calendar info) but am getting this error when I try to add a room
(shows at the bottom of the page):

A PHP Error was encountered

Severity: Warning

Message: Invalid argument supplied for foreach()

Filename: rooms/rooms_add.php

Line Number: 203

After clicking say I get many more errors.

Any suggestions?

I'm getting the same problem :(
I go to add a room (the same error appears at the bottom) and then
once I submit it throws back multiple errors but it does actually add
the room.

I found that the room was added but I got the errors - I decided to
ignore errors.
